how can i model sediment in channel(3phases)?
 
hi
i want to model a channel with sediment,water and air (3phases). how can i do it?
it is immediate for me, please help me.

A number of ways. The easiest way is probably to create 2 continuous fluids, Air at 25C, Water, and a dispersed particulate solid phase to represent the sediment. Turn on buoyancy, initialize the domain with the free surface in place, and other than including the dispersed solid, follow the tutorials on free surface flow.

PS, I hate questions like this. "I need to build a car. How do I do it?"

what??? i don't know how do it so how can i question it???
i read free surface tutorial but i have a model with 3 phases.i want a example or tutorial about it that i read it. is it possible?

The CFX tutorials are the best place to start.
